Fix Adobe Flash Player Issue In Chromium In Ubuntu 14.04
================================================================================
One of the first few [things to do after installing Ubuntu 14.04][1] is to install Adobe Flash Player. Normally, if you install [Ubuntu Restricted Extras][2], Flash Player should be working and you should be able to watch online videos from websites like You Tube etc.
But this is not the case with Chromium and Ubuntu 14.04 combination. While you can easily play You Tube videos etc on other web browsers such as Firefox, Chrome etc, in Chromium you will see Adobe Flash player missing notice:
**Adobe Flash Player is required to display some elements on this page. Install plug-in..**

### Reason for flash player issue exclusively in Chromium: ###
The reason why this issue occurs only in Chromium is that until now Chromium used Netscape Plugin API for Flash support. Starting from Ubuntu 14.04, [Chromium will stop using Netscape Plugin API][3]. Hence, you will face issues with Adobe Flash Player with Chromium.
Now, why this issue doesn’t occur with other web browsers? Answer is because they use Flash version 11.2.
### Fix Adobe Flash Player issue with Chromium: ###
To fix this issue, we’ll be using Pepper Flash Player, a safer and more stable version of Flash Player from Google. An [Adobe Flash Player Pepper installer][4] is available in Ubuntu 14.04 repositories. This installer downloads Google Chrome, extracts Pepper Flash Player and sets it up for Chromium usage.
To install Pepper Flash Player in Ubuntu 14.04, open a terminal and use the following commands:
sudo apt-get install pepperflashplugin-nonfree
sudo update-pepperflashplugin-nonfree --install
Restarting Chromium will do. No need of a system reboot. I hope this quick post helped you to fix Adobe Flash Player issue with Chromium. Any questions or suggestions are always welcomed.

Fix Unity Freezes After Login In Ubuntu 14.04 [Quick Tip]
================================================================================
If you upgraded Ubuntu 13.10 to Ubuntu 14.04, you might end up with **Unity freezing at login time**. You boot in to Ubuntu 14.04, enter your credential and the system just hangs up, freezes. If you are lucky, you might see mouse cursor, background wallpaper but nothing else. **No Unity launcher, no top panel** etc. Basically you will have Ubuntu in an unusable state.
This problem of missing Unity launcher, panel and system freeze can be solved by re-installing Unity. Let’s see how to do that:
### Reinstall Unity in Ubuntu 14.04 to fix system freeze issue ###
Well, since you are stuck with a frozen system, use **Ctrl+Alt+F2** key. This will take you to command line interface (instead of the default graphical user interface). You will be asked to enter your credentials. After you enter your username and password, use the following commands one by one to reinstall Unity desktop.
sudo apt-get update
sudo apt-get install –reinstall ubuntu-desktop
sudo apt-get install unity
sudo shutdown -r now
The last command will reboot your system. After the reboot, you should have Unity working as normal.
### Fixing Unity freeze issue with Nvidia graphics: ###
I don’t have experience with Nvidia graphics but I found some people mentioning additional steps for system with Nvidia graphics card. While the above trick worked for my system, I cannot verify the one below. People with Nvidia graphics, please confirm that the steps below work for your system:
Press Ctrl+Alt+F2 to use command line. And after entering username and password, use the following commands one by one:
sudo apt-get update
sudo apt-get install –reinstall ubuntu-desktop
sudo apt-get install unity
sudo apt-get remove –purge nvidia*
sudo shutdown -r now
Once you have Unity back to normal at next reboot, just reinstall the Nvidia drivers (you had just removed them).
I hope these quick tips help you to recover your Ubuntu 14.04 from a frozen Unity to a working Unity. Any questions or suggestions are always welcomed.
